Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758538, here are decompositions:

31 + 8758507 = 8758538
37 + 8758501 = 8758538
79 + 8758459 = 8758538
109 + 8758429 = 8758538
199 + 8758339 = 8758538
211 + 8758327 = 8758538
337 + 8758201 = 8758538
367 + 8758171 = 8758538

Showing the first eight; more decompositions exist.
